"Paleoindian specialist Kenneth Tankersley believes archaeology is only beginning to scratch the surface of the debate. "Variation in the languages and DNA of American Indians not only suggests there were multiple migrations from a number of different homelands, but they imply that the first wave of people arrived in the Americas more than 30,000 years ago. This suggests archaeologists should be looking in older geological strata." "
DNA is going to reveal it all eventually. We’ll have interactive maps of human migration for at least the past 40,000 years. Kind of exciting and amazing.
